Gérard Debreu (1921-2004) was a French-American economist and mathematician. With Kenneth Arrow he co-developed the Arrow-Debreu model, rigorously proving the existence of general equilibrium prices using tools from topology. He was awarded the 1983 Nobel Memorial Prize in Economic Sciences for incorporating new analytical methods into economic theory, and spent most of his career at the University of California, Berkeley.

In 1954, he published a breakthrough paper, entitled Existence of an Equilibrium for a Competitive Economy, together with Kenneth Arrow, in which they provided a definitive mathematical proof of the existence of a general equilibrium, using topological rather than calculus-based methods.

It was proposed by Kenneth Arrow, Gerard Debreu in 1954, and Lionel W. McKenzie independently in 1954, with later improvements in 1959.
